OK Here comes the Backlash phoenix :lol:
I used Carbon in my Discus Tank, it didn't make any difference that I could see, ended up taking it out, for the Simple reason being, if I ever needed to Treat with Meds, then I would have to muck around and take the carbon out everytime I treated the Tank.
Tank seems to be clear now not sure why, maybe it just needed abit of time to settle down, after I installed the New CF1200.
